Diagnostic Test

  1. TEST FOR INTERMITTENT CONDITION 
    1. Turn the ignition on.
    2. With the scan tool, erase all DTC's.
    3. Move the Driver Seat Switch in the Vertical position three times.
    4. With the scan tool, read DTC's.

      Does the scan tool display this DTC?

      Yes 

      • Go to step  2

      No 

      • The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
      • Perform POWER SEAT SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Memory Seat (MSMD) - Standard Procedure .
